Other changes include: some airports have stopped curb-side baggage check, anything vaguely resembling a knife or lighter may or may not be confiscated (although lighters suddenly stopped being dangerous a year ago), you're sometimes only allowed one carry-on plus a purse, briefcase, diaper bag or the like, non-passengers aren't allowed past security, all passengers must have a document that looks like a boarding pass at most airports to get past security, you may have to put your toothpaste and shampoo in a baggie that may have to be a one quart size, some parking areas close to terminals are closed. But check-in clerks no longer ask you whether you packed your own suitcase.
NAV CANADA also publishes the Canadian Airport Charts (airport diagrams) airport diagrams publication. The information in the Canadian Airport Charts provides pictorial displays of Canadian airport manoeuvring areas found in the Canada Air Pilot or the military GPH 200, and may be reproduced for the sole purpose of assisting pilots during aircraft ground movement operations. Up-to-date information on flight planning procedures and airport services, including fuel, lighting and local prohibitions or procedures is found in the Canada Flight Supplement.

Cases of sexual assault against female travellers have been reported. Always travel in groups and avoid isolated areas, including unsupervised beaches, especially at night. Never leave food or drinks unattended or in the care of strangers. Be wary of accepting snacks, beverages, gum or cigarettes from new acquaintances, as they may contain drugs that could put you at risk of sexual assault.
